Briefly introduce rockery and stone landscape engineering.

Rockery: the floorboard of artificially recreated landscape, which aims at landscaping and sightseeing, fully combines functions, takes earth and stone as materials and natural landscape as the blueprint, and carries out artistic refinement and exaggeration. Rockery can be divided into earth mountain, stone mountain and earth-rock mountain due to different materials.

Taihu stone (a mysterious Taihu stone with various postures, whose color can best reflect the beauty of "wrinkle, leakage, thinness and transparency"), Fangshan stone (its rough, heavy and stocky characteristics are combined with the solemn, bold and large-scale characteristics of northern royal gardens) and quartz stone (thin, wrinkle, leakage and transparency). Thin fingers are uneven; Wrinkle refers to the deep texture on the stone surface and prominent edges and corners; The distribution of leakage marks is moderate and orderly; Finger penetration holes are communicated with each other. The surface of negative stone is round and shiny, with many holes, and the emphasis is on "leakage". Shi Yang's surface is angular, with many wrinkles and few perforations, focusing on "thin and wrinkled". ), lingbi stone (:"three strange and five strange". The three wonders are color, sound and quality, and the five wonders are thin, transparent, leaky, wrinkled and ugly. ), Xuan Shi. Only stones should be old, and the older they get, the whiter they become, just like snow-capped mountains. ), stalagmites (shaped like bamboo shoots), other stone products

(such as wood fossils, pine bark stones. Stone coral, yellow wax stone eggs, etc. )

The functions of rockery mainly include: a, as the main scene of natural landscape garden; b, as a means to divide and organize garden space; c, as a means to decorate garden space and set off buildings and plants by using rock pieces; d, as outdoor natural furniture or devices, as the terrain skeleton of natural landscape garden.

The key points of rockery bottoming are overall planning to the back, scattered twists and turns, intermittent, close bite, safe and stable buffer.

The requirements of the middle layer of rockery are: connecting stones to press stubble, staggering sideways, alternating intermittently, balancing equally, and avoiding braking at attention.

The common foundations in rockery buildings include pile foundation, lime-soil foundation, stone foundation, concrete foundation and reinforced concrete foundation.

The independent or attached landscape layout with rocks as materials mainly shows the individual beauty or local combination of rocks, without complete mountain shape. The main forms of setting stones in gardens are: special setting stones, opposite setting stones, scattered setting stones, group setting stones and rock setting stones.
